FIG. 6 is an enlarged view of part C in FIG. (A) is a cross-sectional view showing the attachment 1a, and (b) is a cross-sectional view showing the attachment 1b. FIG. 5 is a cross-sectional view showing the attachment 1c. (A) is a diagram showing the fixed structure 20, and (b) is an enlarged view of part D of (a).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is an exploded perspective view showing the attachment 1, FIG. 2 is an assembled perspective view showing the attachment 1, FIG. 3 is a sectional view of the attachment 1, and is a sectional view taken along line AA of FIG.

The attachment 1 is mainly composed of a holding member 3a which is a first holding member, a holding member 3b which is a second holding member, a bolt 5 which is a joining member, a nut 7, and the like. The attachment 1 is a member for attaching an object to be fixed to an angle member or the like. The materials of the sandwiching member 3a and the sandwiching member 3b are not particularly limited, but are, for example, steel.

As shown in FIG. 3, one of the sandwiching members 3a has a mountain-shaped portion 4 formed at a substantially central portion in the length direction of the attachment 1 (the left-right direction in FIG. 3). The mountain-shaped portion 4 is a portion having a height higher than other portions. Both sides of the chevron portion 4 with respect to the length direction of the attachment 1 project in a plate shape, a sandwiching portion 6a is formed on the outside of the chevron portion 4, and a joint portion 8a is formed on the outer side of the pinching portion 6a. ..

The side surface of the mountain-shaped portion 4 and the upper surfaces of the sandwiching portion 6a and the joint portion 8a projecting in a plate shape are connected by ribs 11 to be reinforced. The ribs 11 have a substantially triangular plate shape, and are formed near both end portions of the sandwiching member 3a in the width direction (vertical to the longitudinal direction and perpendicular to the paper surface of FIG. 3). The sandwiching member 3a may be formed by joining plate-shaped ribs 11 by welding or the like, or may be integrally formed as a whole.

For example, when the rib 11 is integrally formed, the shape of the rib 11 does not have to be plate-shaped as in the attachment 1e shown in FIG. In the attachment 1e, the rib 11 is formed so that the height gradually decreases and the width increases from substantially the center of the mountain-shaped portion 4 in the width direction toward the sandwiching portion 6a and the joining portion 8a. Further, a part of the rib 11 is cut out on the upper surface of the joint portion 8a in order to avoid interference with the nut 7 and the like. In this way, when the sandwiching member 3a is integrally formed by casting or the like, it may have a form such as the attachment 1e. The form of the rib 11 and the chevron portion 4 is not limited to the illustrated example, and is not particularly limited.

The mountain-shaped portion 4 of the sandwiching member 3a is provided with a notch portion 9 on the side facing the sandwiching member 3b, which will be described later. The notch portion 9 is formed over the entire width direction of the sandwiching member 3a. The notch portion 9 is a portion for avoiding interference with the angle material or the like. In the present embodiment, as shown in FIG. 3, a plurality of angle members 21 are arranged in a substantially T-shape (inverted T-shape in the figure). Therefore, the notch portion 9 is formed in a substantially T shape so as to avoid interference with the angle member 21.

Holes 15a are formed in the joint portions 8a formed on both sides of the notch portion 9 of the sandwiching member 3a and outside the sandwiching portions 6a and 6b, respectively. The hole 15a is a joint with the other holding member 3b.

The sandwiching member 3b is a plate-shaped member and is arranged so as to face the sandwiching member 3a. In the sandwiching member 3b, the portion of the sandwiching member 3a facing the sandwiching portion 6a is the sandwiching portion 6b, and the portion of the sandwiching member 3a facing the joining portion 8a is the bonding portion 8b.

When the sandwiching member 3b is arranged so as to face the sandwiching member 3a, a hole 15b is formed in the joint portion 8b corresponding to the hole 15a of the joint portion 8a. Bolts 5 are inserted into the holes 15a and 15b and joined by nuts 7. That is, the sandwiching member 3a and the sandwiching member 3b are joined by bolts 5 and nuts 7, which are joining members, on both sides of the notch portion 9, respectively. By doing so, as shown in FIG. 3, a part of the angle member 21 can be sandwiched and sandwiched between the sandwiching portion 6a of the sandwiching member 3a and the sandwiching portion 6b of the sandwiching member 3b. The joining member does not have to be the bolt 5 and the nut 7, the nut 7 may be integrated with the holding member, and a female screw portion may be formed in the hole 15a or the hole 15b.

The portions of the sandwiching portion 6b and the joint portion 8b of the sandwiching member 3b are slightly thinner than the portions on both sides in the length direction thereof. Therefore, steps 17 are formed on both sides of the joint portion 8b of the sandwiching member 3b in the length direction so that the wall thickness becomes thicker. Each step 17 is formed along the width direction of the sandwiching member 3b. That is, the sandwiching member 3a is arranged between the steps 17 on both sides of the sandwiching member 3b.

On the outer side of one joint portion 8b of the sandwiching member 3b, a mounting portion 13 extending in a direction protruding from the sandwiching member 3a is formed. The mounting portion 13 is provided with, for example, a hole, and an object to be fixed can be mounted.

The mounting portion 13 may be formed on the holding member 3a side instead of being formed on the holding member 3b. That is, the attachment portion 13 is provided on at least one of the sandwiching member 3a or the sandwiching member 3b. Further, the attachment portion 13 may be formed so as to extend in the width direction instead of being formed so as to extend in the length direction of the attachment 1. Further, the attachment portion 13 may be formed in the height direction of the attachment 1 (in the vertical direction of FIG. 3, above the holding member 3a or below the holding member 3b). Further, the mounting portion 13 does not necessarily have to project in a plate shape, and a hole may be directly formed at any position of the holding members 3a and 3b.

Next, an example of a fixed structure using the attachment 1 will be described. FIG. 5 is a diagram showing a fixed structure 20 using the attachment 1, and FIG. 6 is a cross-sectional view taken along the line BB of FIG. In FIG. 5, the wiring and the like are not shown.

The structure 23 is, for example, a part of a steel tower, a railway overhead wire pillar, a beam between overhead wire pillars, a pillar or a beam of a building, a mechanical foundation of equipment or the like, or a gantry. The structure 23 is formed of a plurality of angle members 21. In the present embodiment, as shown in FIG. 6, a pair of L-shaped angle members 21 are arranged back to back, and are arranged in a substantially T shape as a whole.

As described above, the angle member 21 of the structure 23 is sandwiched between the holding members 3a and 3b, and the attachment 1 is fixed to the structure 23. As shown in FIG. 5, in the present embodiment, an example in which the attachments 1 are arranged at two positions apart from each other with respect to the structure 23 is shown, but the number of attachments 1 arranged is limited to the illustrated example. do not have.

A fixing plate 29 is fixed to the attachment portion 13 of the attachment 1 by bolts 33 and nuts 31. A metal fitting 27 is attached to the fixing plate 29 with bolts or the like (not shown), and the support column of the antenna 25 is fixed by the metal fitting 27. The antenna 25 is, for example, an antenna for a mobile phone, PHS, or the like.

In the present embodiment, an example of the antenna 25 and its fixing member is shown as a fixing object to be fixed to the angle member 21, but the fixing object is not limited to this. The fixed object may be, for example, a signboard, an electronic signage (so-called digital signage), a signboard, an identification board, a display board such as an indicator board, or the like. In this case, the display plate may be directly or indirectly attached to the attachment portion 13 in the same manner as the fixed plate 29 shown in the figure. As described above, the fixed object of the attachment 1 is not particularly limited.

FIG. 7 is an enlarged view of part C of FIG. As described above, a part of the angle member 21 is sandwiched between the sandwiching portion 6a of the sandwiching member 3a and the sandwiching portion 6b of the sandwiching member 3b. At this time, a slight gap 35 is formed between the joint portion 8a of the sandwiching member 3a and the joint portion 8b of the sandwiching member 3b. By doing so, the angle member 21 can be reliably sandwiched between the sandwiching portion 6a and the sandwiching portion 6b.

The notch portion 9 is formed sufficiently larger than the angle member 21 except for the sandwiching portions 6a and 6b in which the angle member 21 is sandwiched. That is, the angle member 21 may have a gap formed between the holding members 3a and 3b other than the holding portions 6a and 6b. By doing so, the attachment 1 of one size can be applied to the angle members 21 of a plurality of sizes.

As described above, according to the present embodiment, since the notch portion 9 corresponding to the shape of the angle member 21 is provided, there is no interference between the angle member 21 and the attachment 1, and the angle member 21 is formed by the pair of holding members 3a and 3b. Can be pinched. Therefore, the attachment 1 can be fixed to the structure 23 without drilling a hole in the angle member 21. In addition, the attachment 1 can be easily attached and detached as needed.

Further, since the steps 17 are provided on both sides of the holding member 3a, it is possible to prevent the holding member 3a and the holding member 3b from being displaced from each other when a force is applied to the holding member 3b in the length direction. Further, since the force applied to the sandwiching member 3b can be transmitted to the sandwiching member 3a via the step 17, the object to be fixed can be more reliably fixed to the structure 23. In addition, in order to engage the sandwiching members 3a and 3b at the step 17, it is desirable that the height of the step 17 is higher than the gap 35 of the joint portions 8a and 8b described above.

Further, if necessary, by installing a plurality of attachments 1 side by side, a large fixed object or the like can be easily attached.

Further, by increasing the size of the notch portion 9 with respect to the angle member 21, it is possible to cope with a plurality of sizes of the angle member 21.

In the present embodiment, the case where the angle members 21 are arranged in a substantially T shape has been described, but the arrangement of the angle members 21 is not limited to this. FIG. 8A is a diagram showing an example using the attachment 1a.

The attachment 1a has almost the same structure as the attachment 1, but the shape of the notch 9 is different. In the following description, the configurations having the same functions as those of the above-described embodiment are designated by the same reference numerals as those in FIGS. 1 to 7, and duplicated description will be omitted. Further, in the following figures, unless otherwise specified, the illustration of the fixed object is omitted.

When fixing to the L-shaped angle member 21 as in the attachment 1a shown in FIG. 8A, a substantially L-shaped notch portion 9 corresponding to this may be used. In this case, the sandwiching portions 6a and 6b need only be formed on one side of the chevron portion 4.

Further, FIG. 8B is a diagram showing an example using the attachment 1b. The attachment 1b has almost the same configuration as the attachment 1, but the form of the holding member 3b is different. A mountain-shaped portion 4 is formed on the holding member 3b of the attachment 1b in substantially the same manner as the holding member 3a.

The sandwiching members 3a and 3b have substantially T-shaped notches 9 in their respective chevron portions 4 facing each other. That is, the notch portion 9 is provided in both the sandwiching member 3a and the sandwiching member 3b. When the notches 9 of the sandwiching members 3a and 3b are joined to each other so as to face each other, the shape of the notches 9 becomes substantially cross-shaped. As described above, the attachment 1b can correspond to a structure in which four L-shaped angle members 21 are arranged back to back and arranged in a substantially cross shape.

There is no problem when the individual angle members 21 are in contact with each other back to back, but as shown in the figure, when a gap is formed between the individual angle members 21, at least, The spacer 37 is arranged in the gap between the angle members 21 in the direction of being sandwiched between the sandwiching members 3a and 3b. By doing so, the plurality of angle members 21 can be reliably sandwiched and fixed by the sandwiching members 3a and 3b.

In each of the above-described embodiments, an example in which the L-shaped angle members 21 are arranged alone or in combination is shown, but the present invention is not limited to this. For example, C-shaped members, T-shaped members, and the like may be arranged alone or in combination. As described above, the present invention can be fixed to an object having a cross-sectional shape other than the L-shape. In this case, the shape of the notch portion 9 may be formed so as not to interfere with the angle material or the like according to the arrangement of the angle material or the like. In the following description, the angle member 21 will be used, but it may be replaced with a C-shaped member or a T-shaped member.

Further, when a plurality of angle materials or the like are sandwiched and a spacer is sandwiched between the plurality of angle materials or the like, the mounting portion 13 is replaced with the spacer 37 as shown in the attachment 1c shown in FIG. The spacer 39 may be sandwiched. That is, in the attachment 1c, the attachment portion is not formed on the holding members 3a and 3b, but the plate-shaped attachment member sandwiched between the plurality of angle members 21 functions as the spacer and attachment portion 13.

As described above, the mounting portion 13 does not necessarily have to be integrated with the holding members 3a and 3b, and may be a separate body if it can be fixed by the holding members 3a and 3b. Further, by designing the shape of the notch portion 9 or the like according to the form of the angle material or the like, it can be fixed to a structure of any form.

The object to be fixed is not limited to an antenna or a display board attached to one angle material or the like. FIG. 10A is a diagram showing a fixed structure 20a. In the fixed structure 20a, a pair of attachments 1d are arranged on different angle members 21 constituting the structure, and the attachments 1d are connected to each other by a brace 45 which is a reinforcing member.

The structure 23a is composed of a beam 41 composed of an angle member 21 and a column 43. One attachment 1d is fixed to the beam 41, and the other attachment 1d is fixed to the pillar 43. The ends of the brace 45 are attached to the attachment portions 13 of the pair of attachments 1d, respectively. In the illustrated example, the brace 45 is arranged in two directions by the two pairs of attachments 1d. A turnbuckle or the like (not shown) is used for the brace 45.

FIG. 10 (b) is an enlarged view of part D of FIG. 10 (a). In the present embodiment, one holding member 3b is joined to the three holding members 3a. That is, a plurality of sandwiching members 3a are joined side by side to one sandwiching member 3b. By doing so, it is easier to attach as compared with the case where a plurality of attachments 1 are provided side by side.

As described above, the attachment 1d can also be used when attaching a reinforcing member to the structure for seismic retrofitting of a building, for example. In this case, the reinforcing member is not fixed to the beam 41 and the column 43, but can be attached to any part constituting the building.

Although the embodiment of the present invention has been described above with reference to the attached drawings, the technical scope of the present invention does not depend on the above-described embodiment. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

For example, it goes without saying that the configurations of the attachments described above can be combined with each other.
